Find the missing base: LOGb(8)=5

Hi, could you help me with this algebra problem please. Thank you

If this is what you mean:

$<br /> \log_b 5 = 8<br />$

You can apply the definition of logarithms, which is that if $\log _a b = c$ then $b^c = a$ . So from $\log_b 8 = 5$ you have $b^5 = 8$ . Can you take it from here?
